Particles of density 3442 kg/m3 are being studied by a manufacturer of air pollution control systems (APCSs). The particles are of various (unknown) shapes and diameters, so the engineers devise an optical technique to measure the terminal settling speed Vt of the actual particles and then plan to calculate some kind of equivalent spherical diameter to use in their APCS performance simulations, which are all based on spheres. The application is typically in a hot exhaust duct, so the tests are in air at 92.4o C and 253.1 kPa. The average Vt is measured to be 0.477 m/s. Calculate all three equivalent diameters as defined in class and below
